Definitions

• the present invention refers to a novel soap composition, particularly to a toilet soap bar for cleansing body skin, which has an improved mildness.
• a general problem in the formulation of soap bars has been that of finding a balance between providing structure whilst both maintaining lathering properties and imparting beneficial mildness to the skin, at a practical overall cost.
• Patent application WO 920844 discloses a skin cleansing bar, which may be soap based and contains 0.5-20% of a silicone gum/silicone fluid. Polyalkyl siloxanes are preferred. This composition improves skin conditioning and moisturisation, and reduces both irritation and dryness.
• Optional ingredients include fatty acid as plasticizer, glycerine as moisturizer and a whole range of vegetable oils as occlusive moisturisers.
• Patent application EP 578,841 discloses a solid soap containing 0.5-7% of a water insoluble silicone ##STR1## and optional ingredients such as glycerine. This product is intended to reduce cracking and flaking of the skin and to improve moisture retention.
• Patent application GB 2,058,822 discloses a soap composition containing 0.01-6% of polydiorganosiloxane of molecular weight 2000 or higher and containing nitrogen and improves the feel of the skin after use.
• Patent application GB 2,143,250 discloses a combination of vegetable oil and silicone oil which is used in a personal cleansing composition.
• Patent application WO 9417172 discloses a syndet-based bar composition containing 0.1-9% of silicone and from 0-25% of soap and 0-35% of free fatty acid.
• Patent application JP 01294797 discloses mixtures of silicone oils and optionally polyols (eg. glycerol) which are used in soaps based on counterions derived from weak bases.
• Patent application JP 01060696 discloses mixtures of silicone oils and optionally polyols (eq. glycerol) which are used in transparent soaps.
• this present invention provides a new soap composition comprising fatty acid soap associated with mildness actives.
• toilet soaps begin to provide other benefits to the skin, over and above their cleansing qualities. These include the agreeable sensation of a lubricated hydrated and silky skin.
• silicones which are applicable to the skin, the following may be highlighted: it is a hydrophobic substance, and thus water resistant, which remains after the rinsing process; it is a lubricant for the skin and hair. At the same time, it provides an improved tactile sensation and does not block the pores of skin.
• the soap composed in accordance with this invention gives a more creamy denser foam, when compared with current state of the art toilet soaps.
• the present invention refers to a composition for soap, based on a conventional soap, with 65% to 85%, by weight, of total fatty acids, to which are added from 1% to 15%, by weight, of a combination of silicones and other emollients. To dry skin, this will give the sensation of soft, silky skin, to a greater extent than other soaps.
• Silicone may comprise 0.5 to about 5%, by weight, of the compositions of the invention.
• the emollients which are suitable for toilet soap, under this invention may be selected from polyols, fatty acids, vegetable, mineral and animal oils, and other emollients which are similar or which may be adsorbed into the silicone chain.
• Glycerin and sorbitol are preferred among the polyols.
• babassu fatty acid and lauric acid are preferred.
• the sunflower oil, corn oil and almond oil among others may be used.
• compositions of the invention may comprise from about 0.5 to about 5% by weight of a first emollient which is a polyol as noted above and up to about 5.0% by weight of a second emollient selected from vegetable, animal or mineral oils, free fatty acids or mixtures thereof as noted above.
• a first emollient which is a polyol as noted above
• a second emollient selected from vegetable, animal or mineral oils, free fatty acids or mixtures thereof as noted above.
• composition of the toilet soap bar may also include a certain percentage of an appropriate and desired perfume, added to the soap mix.
• composition of the toilet soap bar may also include a certain percentage of an appropriate dye or colorant agent, added to the soap mix to impart the desired color to the soap bar.
• the quantities of perfume and coloring agent to be added to the soap mix, prepared in accordance with this invention are not critical, and should be such that they produce the desired coloring and aromatizing effect.
• a cold-rolled soap method is used to prepare a soap bar.
• a previously prepared soap mix for making a toilet soap cake according to the present invention composed of 65% to 85%, by weight, of salts of fatty acids, reckoned as total fatty acids, is placed in a crutching machine (Sigma, for example).
• the glycerine and/or polyols, silicone and other emollients are added in a proportion, by weight, of from 1% to 15%.
• the moisture contents of the mix is then set at between 8% to 20%, by weight.
• an appropriate coloring agent for example: Red Iragon PS paste and/of Orange Iragon II DC
• a soap compatible perfume such as Gemini 699.
• the composition is thoroughly mixed with a suitable stirrer.
• a suitable stirrer Once the mix is homogenous, the conventional stages of the process for obtaining soap or toilet soap in cakes are carried out, these being: rolling (with a Buehler/Mazzoni Roller), compacting and extruding (using a Bonot extruder), cutting of the extruded bar and stamping and wrapping the bar (using a Sigma or Acma Machine).
